| 摘 要： | 基于A/O法的BAF前置反硝化脱氮工艺同时具有A/O工艺和BAF工艺的优点,试验考察了4种A/O体积比(n)对生活污水中COD、氨氮及总氮去除效果的影响.研究结果表明,COD的去除率与n呈正相关;同时该工艺具有很强的硝化和脱氮性能,其出水氨氮和总氮均能达到域镇污水处理厂污染物排放标准(GB 18918-2002)的一级A标准;当n为2/3时,该工艺对氨氯和总氮的去除率均达到最佳,分别为92.7%和70.4%;此外,在回流比为150%,进水流量为16.5L·h~(-1),气水体积比为4:1～6:1,水温为19.5～26.5℃的条件下,O段对TN的去除率72%,发生同步硝化反硝化现象. |

| Abstract: | The BAF pre-denitrification process on the basis of the A/O process integrates the advantages of the BAF and A/O processes.The influence of the four volume ratios of anoxic filter(n) to aerobic filter on the removal effect of the BAF pre-denitrification process for organic matters(COD),ammonia nitrogen(NH3-N) and total nitrogen(TN) in the domestic wastewater was studied.Results revealed that the removal efficiency of COD has positive correlation with volume ratios ofanoxic filter to aerobic filter.Meanwhile... |
